The HEART framework is a new way to improve medical artificial intelligence that helps students learn about high blood pressure. Instead of letting the computer give one answer, HEART lets it look up many pieces of information and then combine them. This approach is called “retrieval‑augmented
Brandon Patterson, a 41-year-old man paralyzed from the chest down after a car crash, is testing something futuristic: a brain-computer interface. Unlike most tech that tracks movement signals, his setup implants electrodes in a part of his brain linked to decision-making. Researchers hope this appr
Around four in every ten people caring for those with memory loss have seen surprising moments of sharpness. That's what a large nationwide study discovered after surveying nearly 6, 000 caregivers and family members. These brief returns to clarity happen to patients with Alzheimer's or other memor
Light-activated cancer treatments sound high-tech—and they are. Doctors use a special light-sensitive drug called a photosensitizer (PS) to destroy unhealthy cells. The trick isn’t just dumping in more light-sensitive molecules. Studies show where those molecules go inside the cell matters more than
Doctors know a lot about cancer, but not all of them take the same steps to protect themselves. A recent survey of 616 women who work in medicine in Punjab, India, found that only some get tested for cervical cancer or receive the HPV vaccine. The study shows that the type of job a doctor does, how
Back in the 1800s, two scientists named Hansen and Neisser both studied leprosy. Hansen published findings first, naming the bacteria Mycobacterium leprae. Neisser followed a year later, but never said Hansen was wrong or ignored his work. Yet over time, a story grew that Neisser tried to take credi
Weight loss medications like Ozempic and Wegovy have helped many people shed pounds, but a hidden cost might be waiting. New research shows people often judge those who use these drugs more harshly than those who lose weight through diet and exercise. In one study, over 1, 300 participants ranked a
A small team of British soldiers and doctors jumped from a big airplane to Tristan da Cunha, the world’s most isolated island. They brought medicine and oxygen because a man on a cruise ship was sick with a possible hantavirus infection. The flight started from England, stopped in Ascension Island,
Scientists use a special kind of MRI that tracks how water moves in body tissues over tiny slices of time. Called time-dependent diffusion MRI, it helps doctors see details smaller than what regular scans show. Water molecules dance around in healthy and sick tissues differently. By watching this da
Sixty-year-old Shed Boren got the kind of news that used to mean immediate goodbye plans. Doctors told him his kidney cancer had spread everywhere—lungs, hips, bones. Breathing was hard. Without treatment, he had months. With new drugs that teach the body to attack the cancer itself, he lived instea
